Hi Guys

I have a hot water tank in my airing cupboard seen below and a cold water tank in the loft. I understand this is an open vented system. I'm trying to understand what the valves do below. I can see 7 in total which are numbered. Can anyone shed any light?

Thanks RJC. If it helps I have taken another look on how they are connected.

  1. This one splits. One side goes to the top of the cylinder and the other to downstairs.
  2. Doesn't connect to the hot water cylinder. It looks like it goes from the loft straight to downstairs.
  3. Again this one doesn't connect to the cylinder it goes from loft to downstairs.
  4. This one connects to the bottom of the hot water cylinder on the right hand side.
  5. Bottom of hot water cylinder on the left.
  6. This connects to a Honeywell diverter valve.
  7. Connected to diverter valve.
 
Thanks guys. I think I'm getting there.

  1. This feeds hot water to our ensuite shower which is a power shower. The pipe directly above the cylinder is the vent pipe.
  2. Supplies cold water to the tank in the loft.
  3. Not sure on this yet. Cold to touch.
  4. Cold water feed to cylinder.
  5. Hot water coil.
  6. Not sure on this yet. Some sort of diverter.
  7. Not sure on this yet. Some sort of diverter.

Thanks Siliconslave/RJC.
